* I made the following modifications, be sure to readd these when * Added "gaim_ ## " to the namespace * Changed the lib macro to use /lib/gaim instead of just /lib * (why does gaim do that in the -DLIBDIR autoconf thing anyway?) * BinReloc - a library for creating relocatable executables * Written by: Mike Hearn <mike@theoretic.com> * Hongli Lai <h.lai@chello.nl> * http://autopackage.org/ * This source code is public domain.
